"reaper" is not picking up new changes to my application???

Hi,

Can anyone shed any light on why "reaper" (whilst seemingly working re
restarting my mongrel ruby process) does not pick up changes to my
application?  (e.g. changing a title in a view for example).   It''s
like the
"mongrel_rails start  etc..." is just restarting the current process
but
ignoring the new details re where the new application directory is.   That
is with capistrano the new releases are put in different directories, and
are referenced in the command line options to "mongrel_rails", however
it
seems these are being picked up.    I basically have to do a "reaper -a
kill" and then a "nohup script/spin" to get it to recognize the
new
application directory.

Here''s an example of the scenario when I run reaper, the ruby processes
is
restarted, but it doesn''t pick up the new directory (i.e. application
changes).

-- CONSOLE OUTPUT ---
[root@home ~]# cd /u/apps/equity/current/

Re: "reaper" is not picking up new changes to my application???

i really don''t know about reaper (as i''m not using it), but i
guess
your problem is with the symlink "current". you are calling reaper
from that directory (in  your example: /u/apps/equity/releases/
20090209050120) and it does never leave it. as it seems you need to
add some code/script to leave the current directory and reenter
"current" after the symlink is updated.

from the top of my head i'' think about solving this with a simple
rake- or capistrano-task.

I think I see what you''re getting at - this is actually the result of
running the out of the box capistrano script - here''s the cap deploy
output

Re: "reaper" is not picking up new changes to my application???

Still stuck on this.  I made sure I wasn''t in the "current"
directory when I
did the call to "reaper" and I still get the same result, i.e. whilst
the
process restarts it does not restart with the latest application updates
(made available via the new application being put in a new "releases"
directory, and then capistrano change the sym link for "current" to
this new
directory).

Question - Is a "reaper" restart action supposed to update an
application?
That is, is the out-of-the box Capistrano command
"/u/apps/equity/current/script/process/reaper" really supposed to
update any
changes to an application (via a "cap deploy")?

Re: "reaper" is not picking up new changes to my application???

don''t restart reaper, but:
  stop it,
  set symlink current,
  cd to current,
  start it.
